Heat Stop Refractory Mortar

All national building codes specify refractory mortar conforming to ASTM C-199 for installing firebrick and clay flue linings in masonry fireplaces and chimneys.

Easy to use, economical and versatile, HEAT STOP® resists temperatures well above 2000° F, assuring code compliance and a quality installation. Regular cement or mortar found in most mortar mixes resists temperatures up to 600-800° F, but residential installations operate well in excess of 800° F.

You can purchase Heat Stop from your local masonry supply store, or you can order conveniently online by visiting our authorized dealer at www.MyBuildingSupplyStore.com

In addition to refractory products, you can purchase other masonry supplies, such as pizza ovens, cleaning and repair products, admixtures and coloring agents, and more, at their online store.
